Marina Restoration

Land and Water Services (LAWS) use James fisher Prolec’s dredging monitoring system, pcX-Pro for Cornwall’s marina redevelopment scheme. 

Contractor 4Recycling has been working alongside dredging specialist Land and Water Services to find a solution to treat and reuse more than 32,000 tonnes of PCB-contaminated sediment.

Dredging control software

Land and Water services' machine, a Hitachi ZX280, was used on an eight-piece Ravestein pontoon. To achieve the highest accuracy on this job and to reduce material overage, the machine was equipped with James Fisher Prolec’s flagship dredging control system pcX-Pro. The system utilised marine grade AS7 angle sensors and a combination of one RTK GNSS antenna with James Fisher Prolec’s unique CANBUS heading compass.

pcX-Pro’s ability to define avoidance zones combined with highly accurate positioning meant the containment of sediment was much easier compared with other solutions available. In addition to this, a shadow mode system was also installed in the supervisor's office. Using this remote system, full access to all views and a clear image of job progress was available. Again showing the ability of James Fisher Prolec to tailor our systems according to customers requirements.
